What do fall arrest systems do?
A fall arrest system is a system that arrests an employee in a fall from a working level and minimizes arresting forces.
What are the three main components of a fall arrest system?
Harnesses, lifelines/lanyards, and anchorages
What are some of the rules for a fall arrest system in the event of a free fall?

To reduce the amount of arresting force.
What is a lanyard?
